Title: Improvements in the colouration of textile materials
IPC: D06P3/42
Filed: 1933-11-17
Abstract: Cellulose esters or ethers, dyeing; printing; dye preparations.--An aqueous dispersion of a water-insoluble arylaminoanthraquinone dyestuff, for use in dyeing cellulose ester or ether materials, is obtained by diluting with water, in presence of a dispersing agent or protective colloid, a solution of the dyestuff in a water-soluble organic base, the use of a solution of 1 - oxy - 4 - (p - acetylaminophenylamino) anthraquinone in pyridine (cf. Specification 411,877) being excepted.  Such dispersions give dyeings of greater depth than are obtained with the use of a solvent other than a water-soluble organic base.  Specified arylaminoanthraquinones are the 1-phenylamino-, 1-m-tolylamino-, 1 - hydroxy - 4 - phenylamino-, 1-amino-4-phenylamino- and 1-methylamino-4-phenylamino-anthraquinones and the arylaminoanthraquinones described in Specifications 402,391, 402,392, 402,393, 416,611, 416,612, 420,591, and 420,593. Specified water-soluble organic bases are pyridine, quinoline, isoquinoline, piperidine, butylamine, amylamine and triethanolamine.  As dispersing agents are specified soaps, sulphuric acid esters of higher aliphatic alcohols, formaldehyde-naphthalenesulphonic acid compounds, alkyl-, cycloalkyl- and aralkyl-sulphonic acids, sulphonic acids from mineral oils, tar oils and their products of condensation with alcohols, and the dispersing agents described in Specifications 219,349, 224,925, 242,393, 242,711, 269,960, 273,819, 273,820, 322,737, and 323,788, [all in Class 15(ii)].  As protective colloids are specified glue, gelatine, sulphite cellulose waste liquor and lignin sulphonic acids. The dyestuff is preferably heated with the water-soluble organic base and the solution diluted with a hot aqueous solution of soap or other dispersing agent.  The solution is further diluted if a dye-bath is required or is incorporated with a thickener if a printing paste is required.  In an example, a scoured cellulose acetate knitted fabric is dyed blue by treatment for 1\ba1/2\be hours in a bath obtained by diluting with soap solution a solution obtained by dissolving 1-amino-5-phenylamino-4 : 8-dioxyanthraquinone in boiling pyridine and adding turkey red oil, the temperature being raised from 20 to 75 DEG  C. during the treatment.  According to the Provisional Specification the water-soluble organic base may be added to a suspension or dispersion of the dyestuff.

Title: Process and apparatus for recovery of starch and gluten by washing a dough of wheat flour
IPC: C08B30/04
Filed: 1965-07-29
Abstract: In a process for the recovery of starch and gluten from a dough of wheat flour, wherein water supplied to a recovery region carries away starch while gluten accumulates into lumps in the recovery region, the gluten lumps are subjected to a repeated spreading operation in various directions, whereby the lumps are shredded, flattened and to some extent disintegrated, so that embedded starch granules are uncovered, the gluten being allowed to resume its lump shape after spreading.  The apparatus described in Specification 1,094,145 may be used.  The dough, from inlet (5), while being sprayed with water from pipes (8-11) (Fig. 1, not shown), is transported cross-wise and lengthwise of trough (3) by means of stirrers (17), blades (21) and scrapers (18) revolving about central shaft (1).  In operation, stirrers (17) tear the dough, while starch is flushed therefrom at the imperforate end (6) of the trough, and then scrapers (18) spread and flatten the dough or gluten against the perforated bottom parts 14 through which liberated starch is continually flushed by the wash liquid. During their rotation, scrapers (18) catch gluten lumps, push them along the trough bottom, and repeatedly lift them out of the trough and return them thereto.  The scrapers are angled so that the dough or gluten is propelled towards exit (7). Sabre-like means (21) pinch the gluten lumps between their edges and the trough bottom so as to shred the material and expose the starch to the wash liquid. The starch suspension is discharged via pumps (29) and recycled so that gluten particles may be returned to the recovery region.

Patent GB-779136-A (GB)
Title: Improvements in or relating to self-lubricating bearing elements
IPC: F16C33/20
Filed: 1952-12-22
Abstract: Self-lubricating bearing elements are produced by forming and moulding a mixture of an epoxy resin to which is added a hardening agent, and a finely divided solid lubricant such as graphite or molybdenum sulphide, either alone or in admixture.  In one example, to 500 g. of the product of condensation of diphenylolpropane with epichlorhydrin melted and maintained at a temperature of 140 DEG  C. is added little by little whilst agitating 325 g. of dry non-colloidal finely powdered graphite previously brought to a temperature of 140-150 DEG  C.  To this is added 150 g. of phthalic anhydride as hardening agent.  The mixture is maintained for one hour at 140-150 DEG  C. under reduced pressure, thus assuring the de-gasefication of the mixture and its homogenization.  The mixture is then poured into an annular mould previously heated and coated with silicone to prevent sticking. The resin is then hardened by raising the temperature to 180-190 DEG  C. and maintaining it there for about three hours.  The resin will then have reached the final stage of condensation.  The temperature necessary for hardening is the greater the bigger are the dimensions of the element, and large elements should be re-heated to 150 DEG  C. for two to three hours. In another example, 100 g. of the product from the condensation of diphenylolpropane with epichlorhydrin is mixed at room temperature with 45 g. of graphite powder as used in the previous example.  When the mixture is throughly homogeneous, 10 g. of triethylenetetramine is added as a hardening agent.  The resulting mixture is first heated to 40 DEG  C. and then moulded as in the first example.  The filled mould is then placed under a vacuum of several millimeters of mercury for thirty minutes, the temperature being maintained at 40 DEG  C. The mould is then left for twenty-four hours.  Further examples describe the replacement of the graphite by powdered tin or powdered lead.
